Consider a two-stage plant-retailer supply chain. Lead time for the plant to fill retail orders is one week. The plant produces exactly to demand and does not keep inventory. Desired safety stock at the retailer is equal to half-week demand, and future demand is estimated by the average of the past two weeks. Find the impact on plan production (customer orders) if demand permanently increases from 100 to 110 units per period

Scenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?

Consider a two-stage plant-retailer supply chain. Lead time for orders is three weeks. Safety Stock is equal to one week's demand and future demand is estimated by the average of the two past weeks. Find the impact on plant production (customer orders) if demand changes from 100 units a week to cycle between 90 units and 110 units per week

An auto parts maker in Indonesia produces one of the spare parts brands with a daily production rate of 200 units. The company has forecast that the annual demand (D) will be 12,500 units over the next year and the company operates 250 business days per year. The cost of preparing an order is $30 per order, and the cost of maintaining one unit per year is $2. What is the optimal quantity to produce?
Peerless Products, Inc. Imagine that Peerless Products, Inc., a well-known manufacturer of consumer electron- ics, decides to expand its manufacturing in China. The CEO assigns the task to the vice president of manufacturing, and within two years, the company has a plant up and running in Guangdong. Unfortunately, however, Peerless has no overall end-to-end supply chain capability to account for the fact that its lead times have increased by four weeks. This, in turn, has an impact on how the company sells its products, takes orders, plans distribution, sizes warehousing, and manages inbound and outbound logistics throughout the global markets being served by the Chinese plant. In short, although the company has lowered its product costs, it has increased its supply chain risk and possibly raised its total cost of ownership—taking into account the impact on lost sales. According to Accenture, Inc., risk in the context of global operations may be placed into three buckets:…
Demand for devil’s food whipped-cream layer cake at a local pastry shop can be approximatedusing a Poisson distribution with a mean of six per day. The manager estimates it costs $9 to prepare each cake. Fresh cakes sell for $12. Day-old cakes sell for $9 each. What stocking level isappropriate if one-half of the day-old cakes are sold and the rest thrown out?
A mobile phone producer has fixed costs of 1,5 m $ and variable costs of 800 $. It sells its phones for 1.100 $. A bakery produces bread rolls with variable costs of 1 $ and sells them for 1.5$. Its fixed costs are 30.000 $. Calculate the break-even volumes for both firms.
Annual demand for a product is 8,840 units; weekly demand is 170 units with a standard deviation of 65 units. The cost of placing an order is $90, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.90 per unit. Suppose the production manager is told to reduce the safety stock of this item by 125 units. If this is done, what will the new service probability be?
